Dreamweaver CC Compatibility
In the Download center, a ZXP Version of eCart is available to install into Dreamweaver CC.
Before installing the eCart ZXP Extension, make sure you have installed the Deprecated Server Behaviors extension that Adobe has made available, see this tutorial for details:
While installing the extension on Mac OS, you may encounter an Error stating:
"Failed to update database, the extension will not be installed"
This is a bug in the CC Extension manager that will be corrected by Adobe soon, The extension has, in fact, been installed and can be accessed through the menus in Dreamweaver.
